OMAP-L138: CVDD vs RVDD without DVFS

$
0
0

Part Number:OMAP-L138

According to this guide... processors.wiki.ti.com/.../OMAP-L138_Hardware_Design_Guide

For supporting different voltage operating points, the following rules must be followed:

  • CVDD should not exceed RVDD
  • RVDD should not drop below 1.2V regardless of CVDD voltage or operating point

1. Can CVDD exceed RVDD if DVFS is not implemented (static supplies) ie. CVDD=1.3V; RVDD=1.2V ?

2. Can RVDD be operated anywhere above its Vmin=1.14V as per datasheet, or is 1.2V the actual Vmin as per above?

We have an old PCB design that is "pre-456MHz" but populated with 456MHz parts, and ties RVDD to the other 1.2V static supplies...
